Twitter is jumping into the Firefox mobile mania, committing to build an app to the forthcoming platform.

The microblogging site announced today that when devices running Mozilla's browser-based operating system begin to be shipped to consumers in the next couple of months, it will have an app for the mobile platform in its Firefox Marketplace.

"Similar to our other mobile apps, Twitter for Firefox OS has a rich interface, featuring the Home, Connect, Discover and Me tabs, as well as the search and compose Tweet icons, so you can easily find and send Tweets from anywhere in the app," Twitter engineer Manuel Deschamps wrote in a company blog post today.

The new app will also feature Web Activities, a feature unique to Firefox OS that allows users to tweet photos from within any app that supports the feature.

Like its desktop cousin, Firefox OS runs Web apps written in Web languages like HTML, CSS, and JavaScript, but it also features phone-specific interfaces for things like monitoring battery life and phone orientation.
